here is the code for creating user with email and password
...ANSWER
Answered 2022-Feb-27 at 15:33Your User
class has two constructors:
- One that takes no arguments.
- And one that takes 6 string values as its arguments.
In the two screenshots you are trying to construct a User
object:
- First with a single string value,
- And then with 5 string values.
Since neither of these calls matches the constructors you defined, the compiler is unable to compile your code.
To allow constructing a User
, makes sure you either add constructor overloads for the parameters you want to pass, or pass the parameters that match with the constructors you defined.

QUESTION
I am creating a hospital management system in which I have 2 classes namely AddDoctor and AddPatient which takes the input from user about their details and stores them into their respective files. I now want to create an Appointment class in which I can assign a patient with a certain ID to a doctor with a certain ID which are read from the files. This would be very easy if Java supported multiple inheritance, but since it doesn't, I'm stuck on how I could do this task.
Following is my AddDoctor class
...ANSWER
Answered 2022-Jan-24 at 14:56Simple solution is using composition create object of doc and patient in appointment class and get doc and patient id from user or create one using objects and write it in third file.
In case of Id you need to search info from file. In case of new information, as you will be creating object of doctor and patient. first right them in their files and then store data in third file as you want.
If it answer your question let me know.
QUESTION
I have a simple app that modifies the product and gives the editor to select "Others did also buy this products".
It all works fine and I can save the values I need when the editor saves but I can render them out in a loop with liquid. No matter what I try, I get one iteration no matter how many products I select. The data I save in my metafield looks like this (sorry for the bloated json I'll cook it down and only use the props I need when I can get the loop working :)
As you can see it is a array with 2 objects inside and I don't get why I can't loop them like this in liquid :
...ANSWER
Answered 2021-Oct-18 at 11:37Assuming you are using the new Metafield type json that returns the json_string. To loop over your metafield value, you would have to access the value using value property.

Here's the body of the HTML i'm trying to add rows to.

QUESTION
I'm a newbie in Excel VBA, so need some help. Thanks in advance.
I've a table ('Tabel26') where the number rows change depending on the users choice. All cells in each row has data validation (drop down), which works fine. And my wish is that when the users selects a certain value/text from the dropdown menu in column 16, the value in column 15 change to a specific value + alert the user with a message.
With my present code - added at the end of this - it works fine when I have 1 row in the table. But doesn't work when 2 or more rows... And I'm using range().columns() because the whole table can move down depending on a table above, which has the same features; add/delete rows. So I can't use range('cell#'). And please don't be confused by the text, it's in Danish.
Maybe I need a count.rows and/or a loop, but not sure how.
CODE:
...ANSWER
Answered 2021-Feb-10 at 08:31You need to localise the action to a single cell. so ensure that your cell is a single cell in column 16 of the table then operate on the cell 1 column to the left relative
